Applications
FX-PCV1826 controllers are well-suited for commercial zoning applications and can be used
for pressure dependent VAV box applications where no differential pressure tranduser (DPT) is
required.
Note: At Controller Configuration Tool (CCT) 13.0 or later, using Release Mode 10.1, the PCV18
Series controllers can be configured as either N2 devices or as standard BACnet
devices. This ability provides a potential cost-effective protocol upgrade path for existing
customers and should be considered when you install the controller.
Important: When you receive an FX-PCV18 Series controller from the factory or upgrade the
firmware or main code, the controller defaults to using the MS/TP communications protocol.
The Load Summary screen of CCT shows the connection as Wired Field Bus, indicating that
the MS/TP protocol is in use. If you have an N2 application, the Load Summary screen indicates
that you need to switch the communications protocol to N2.
These FX-PCV controllers feature an integral digital pressure sensor (FX-PCV1832 model only), a
damper actuator, and a 32-bit microprocessor. The controller's small package size facilitates quick
field installation and efficient use of space for field replacements, while still enabling precision
control performance.
Note: Connecting an FX-PCX to the FX-PCV via the SA Bus connection is not supported.

Setup and adjustments Important: Electrostatic discharge can damage controller components. Use proper electrostatic discharge precautions during installation, setup, and servicing to avoid damaging the controller. Setting the device address FX-PCV18 controllers are subordinate devices on N2 buses. Before operating field controllers on a bus, you must set a valid and unique device address for each controller on the bus. -
Page 25: Setting The Eol Switch
Setting the EOL switch Each field controller has an EOL (End of Line) switch, which, when set to ON (up), sets the field controller as a terminating device on the bus. See Figure 3 for the EOL switch location on the field controller. -
